How Oil-Air Lubrication Controls Lubricant Consumption?

Why Does Lubricant Consumption Matter?

Lubricant is an essential operating cost for industrial equipment, particularly in production lines with numerous bearings and long operating hours.

However, high oil consumption does not necessarily mean that a machine requires more lubricant. Some of the consumption may result from excessive delivery, leakage, unsuitable lubrication settings or an inefficient distribution arrangement.

Oil-air lubrication offers a way to control oil delivery by metering lubricant according to the requirements of the selected application.

The objective is not to minimize oil consumption at any cost. It is to supply the quantity required for effective lubrication while avoiding unnecessary waste.

How Does Metered Oil Delivery Work?

An oil-air lubrication system delivers a controlled quantity of oil into a continuous compressed-air stream. The air transports the oil through the pipeline toward the lubrication point.

The required oil quantity depends on factors such as bearing type, dimensions, speed, load, lubricant viscosity and equipment manufacturer's recommendations.

A correctly designed system can provide different delivery settings for different lubrication points where the selected components and control arrangement support this approach.

This makes it possible to tailor lubricant delivery to the actual application instead of applying the same quantity indiscriminately across the entire production line.

Why Can Excessive Lubrication Increase Costs?

When more lubricant is supplied than the application requires, the excess may contribute to leakage, accumulation or additional cleanup work. Depending on the equipment and lubrication method, excessive supply may also create unwanted operating conditions.

The problem is not that all excess oil is automatically wasted; some applications require continuous replenishment or higher delivery rates because of their operating conditions.

The important question is whether the delivered quantity matches the actual lubrication requirement.

A review of oil consumption should therefore examine both the quantity supplied and the condition of the lubricated components.

Precision Lubrication Does Not Mean Simply Reducing Oil Flow

Reducing oil delivery without proper engineering can lead to insufficient lubrication, increased friction and premature component damage.

A suitable oil-air lubrication design should establish the required delivery quantity for each point and verify that the distribution arrangement can deliver it under actual operating conditions.

Engineers should consider:

Bearing type, speed and load.

Lubricant grade and viscosity.

Oil metering settings.

Pipeline length and routing.

Distributor configuration.

Compressed-air pressure and quality.

Operating temperature and contamination conditions.

Where the system supports individual adjustment, the oil supply can be configured to meet the needs of different lubrication points.

How Can Plants Measure the Potential Savings?

Before upgrading an existing lubrication system, collect baseline data such as monthly lubricant purchases, actual consumption, operating hours, leakage, maintenance work and the number of lubrication points.

After the new system is commissioned, compare consumption over a representative operating period while accounting for changes in production output and equipment utilization.

A practical assessment should also track bearing condition and maintenance outcomes. Lower oil consumption is not a successful result if it is accompanied by inadequate lubrication or increased component failures.

For investment decisions, measured data are more reliable than assuming a fixed percentage reduction for every plant.

Why Does System Design Matter?

Oil consumption is influenced by the complete lubrication arrangement, not just the pump.

The main station, metering components, distributors, pipelines and lubrication points must work together to deliver the required oil quantity. Poorly selected components or an unsuitable layout can undermine the intended performance.

A site survey helps establish the number and location of lubrication points, their individual requirements and the most appropriate distribution arrangement.

Commissioning should then verify the configured settings and confirm that the system operates as intended.
